Fi'ggres Z-and -'3 are "respectively; fr'agmentary;- plan Views showing the press heads-closed"bn-the opposite sides of the -'-projecting 'portion-of'the expanderfi'il As here illustrated? th'e'jpress' heads "I112 are provide'd with supportin'gpl'ates "or brackets .8 on:

"their outer faces, these brackets "being "hinged' together at I to a bracket I I forming part of the machine frame, beyond the bend of the U formation of the wrapper. The heads have a pivotal or scissors-like closin movement. The plates are secured to the press heads by screw bolts HA. The heads I, 2, are internally heated in any suitable manner. The sides of the wrap per are in heat conducting relation to' the press heads. Each form 3 is spatulate in general form and the edge at the bend of the U formation tapers or inclines outwardly from the upper end of the form to the lower, while the other or front edge is substantially vertical, all to conform to the taper of shirt sleeves from the cuff to the shoulder.

The forms are mounted on a carriage I3 suitably mounted on a base I4 of the frame and have a fore and aft shifting movement to carry the forms into and out of position between the press heads I, 2. The press heads I, 2, are of sufficient height to press the longer shirt sleeves from the shoulder to the cuffs. In pressing shorter sleeves, the press heads lap on the front, back and yoke of the shirt, which are subsequently pressed on different machines.

As here shown, the press heads of each pair are movable from open position, Figure 3, into closed position, and then subsequently the press heads I are moved into pressing position towards the heads 2, so that both heads'are in the position shown in Figure 2. Thus, during'the pressing operation occurring when the press heads 2 move into pressing position, the press heads 2 move in an arcuate path about the axis of the hinges II]. The compression and deformation of the pad during the arcuate movement causes slack to develop at S, Figure 7, beyond the edges at the open side of the U formation of the body of the form, which slack is taken up by the expander, as will be hereinafter set forth. The bend of the U formation of the wrapper 4 is reinforced against undue warping or creasing by a backing strip I6 supported from the bracket II.

As seen in Figure 4, each form 3 is double walled and formed up of two sheets of metal spaced'apart and secured together to form an internal steam chamber 2|, to which steam'is supplied to heat the form, or the body thereof, in any suitable manner, as through inlet and return pipes P, PI. The body of the form is covered by a padding 22. The padding 22 takes the form of a sleeve folded U shaped, and the layer of the padding around the inner face of the bend of the U formation of the form is held from undue displacement as by a rod 23 anchored, as by a screw 24, Figure 1 to the carriage I3, the rod extending upwardly into the form along the bend of the U formation. The rod is resilient and biased to press the internal layer of the padding toward the inner face of the body of the form at the bend of the U formation. Heretofore in machines where the garment sleeve has been dressed or sleeved on the form, the form has been unprovided with a pad. In the present machine, the body of the form being flat or spatulate with double walls of thin sheet metal spaced apart to provide a chamber for a heating medium, provides a construction by which the paddings on the form and on the expander are kept dry.

Each expander is formed of a strip of sheet metal covered by a padding 26. It is supported and operated by mechanism including an angle lever 21 pivoted at 28 at its angle to the carriage I 3.. This mechanism embodies resilient means .4 to cause the expander to have a yielding followup action in the sleeve.

In the illustrated embodiment of the invention, the resilient means is embodied in one arm 29 of the angle lever, which arm extends upwardly into the body of the form and is pivoted to the expander 5 at 30 between the upper and lower ends of the expander, the arm 29 being a leaf spring. The other arm of the lever 21 extends forwardly in front of the form where it is provided with a handle 3I. The pivoting of the arm 29 to the expander between the upper and lower ends thereof causes the expander to have an equalizing action to conform to the sleeve, and the resilient arm 29 causes the expander to have a follow-up action. After the sleeve is dressed on the form when the form is in its position out from between the press heads, the expander is operated to stretch the shirt sleeve widthwise.

The operating levers 21 for the expanders may be operated in any suitable manner, and as here shown they are operated manually, or their operation controlled. They are held in their operated position by friction latches 32. Each latch 32 is pivoted at 33 to the forward extending arm of the companion lever 21 and has a shoe 34 coacting with an arcuate friction face 35 in a curve struck from a center eccentric to the pivot 28 of the lever 21. The movement of each latch is against a returning spring 36. The latches are released by power means hereinafter referred to.

The power utilized for operating the movable elements of the sleeve press is compressed air. The actuators or motors are of the cylinder and piston type, and. the'flow of air thereto controlled by valves.

The numeral 40, Figure 1, designates a cylinder and piston motor used to shift the carriage I3 to carry the forms into position between the pressing elements or heads, and M designates a cylinder and piston motor for shifting the carriage to carry the forms out of position between the pressing elements. The motor 40 is of greater capacity, or strength, than the motor M and when energized overrules the motor 4|. The piston rod 42 of the motor 40 is connected at 43 to one of a pair of swinging links 44. These links are pivoted at their lower ends at 45 to the base of the frame I, and at their upper ends at 46 to thecarriage I3. The links 44 are paired with another set of links 41, the links 44 and 41 being arranged to have a parallelogram action to swing the carriage I3 horizontally to carry the forms into and out of position between the press heads I, 2. The piston rod 48 of the motor 4| is connected at 49 to one of the links 44. The momentum of the carriage I3, when it approaches the limit of its outward movement, is dampened by a dash pot 50, the movable member of which has a head 5I arranged in the path of a shoulder 52 on one of the links 44. The actuating mechanism. for the carriage I2 forms no part of the invention.

The motor for effecting the movement of the press heads I about the axis of the hinges I0 into straight position, is here shown as a cylinder and piston motor 53, Figure 2, the rod 54 of which is pivoted to the joint of the toggle links 55 and 56, the outer ends of which links are pivoted at 51 and 58 to the heads I.

When the motor 53 is energized, the toggle links 55, 56, are straightened from the position shown in Figure 3 to that shown in Figure 2, and the press heads I are moved into the position shown in Figure 2 before the press heads 2 are 4.
